Abstract

In the promotion of photovoltaic in the whole county, it is more and more important for distributed photovoltaic to participate in market-oriented transactions. Market based trading can realize the return on investment of users, promote the proportion of renewable energy, strengthen the willingness of time-shifting load to participate in source load interaction, and finally help to achieve the goal of carbon neutralization. In order to improve the local consumption capacity at the end of the power grid through market-oriented trading, this paper proposes a coordinated control method of local consumption based on multi-party cooperative game trading. The price is determined through the Stackelberg game between distributed photovoltaic investors, power grid and users, which is optimized by the improved particle swarm optimization method. The user value-added services are considered, the method of determining the revenue of value-added services by introducing load transfer coefficient, output increase proportion and power saving benefit coefficient is realized. Finally, an example is given to verify the effectiveness of the method.
